Yes, the City of San Antonio Development Services Department requires a building permit for window replacements. In 2026, the standard flat fee for a residential building permit is approximately $150, though some projects may be charged $50 per window depending on the scope of structural changes.
Due to the intense Texas heat, upgrading to ENERGY STAR® certified windows can save San Antonio homeowners between $400 and $750 annually on cooling costs. CPS Energy also frequently offers rebates for energy-efficient upgrades that can further offset the initial investment.
For a typical mid-range project in 2026, homeowners pay between $850 and $1,250 per window installed. Budget-friendly vinyl options can start as low as $310 per unit, while premium fiberglass or wood windows can exceed $1,800 per unit.
To meet 2026 ENERGY STAR requirements for the South-Central climate zone (which includes San Antonio), windows must have a maximum U-Factor of 0.28 and a Solar Heat Gain Coefficient (SHGC) of 0.23 or lower to effectively reject solar heat.
